S t r a n d A n c h o r s

Con-Tech Systems Ltd. was founded in 1985 and is a family owned company. Since incep-tion our primary focus in the initial stages was manufacturing post-tensioned Strand Anchors for geo-technical construction. Since that time, not only have we remained close to our roots with our innovative Strand prod-ucts, but we have also devel-oped and promoted many other unique and innovative products to allow our customers to com-plete many difficult projects.

Con-Tech has completed strand projects as small as one anchor to projects containing thousands of anchors. We have completed projects with anchors as small as one strand, to ninety-two strands; still the largest anchor ever manufactured in the world. With these wide selections of products still available to our customers today we are abe to service not only large interna-

tional contractors but also small owner operators. We have the ability to produce anchors with standard corrosion protection systems and are also able to adapt to special project corro-sion requirements as needed. Through our several production plants and offices located across Canada and the USA; from B.C. to Ontario, from Washington State, to North Carolina and Florida, we are able to service any of your project needs.

Recognised as one of the strongest, most flexible and cost effective anchor systems in the industry, Strand Anchors are in use throughout North America. Our unique encapsulation process ensures that the Strands bond length is not contaminated with the grease from the free length. Strand Anchors are typically used for either permanent or temporary tie down and tie back anchors in either rock or soil. Examples include hydroelectric dams, wind tower foundations, slope stabilization and excavation shoring.

Transportation of anchor tendons on reels coiled or looped. Therefore only small stor-age and assembly area are required.

Cutting of length of anchors on job site pos-sible to suit local ground conditions.

Installation of flexible anchor tendons un-der extremely tight space conditions.

Less danger of contact with overhead pow-er lines, because anchors are not as rigid as bars.

High yield point (1570 N/mm2 = 227 KSI) and low E-modulus of 20000 N/mm2 = 29000 KSI indicates that the strain of strand is greater than that for 150 KSI bars.

With our strand anchors more than one tension element in each anchor guarantees higher safety versus single bar anchors.

Our slim line strand coupler allows for easy splicing of even multiple strand anchors.

Corrosion Protection Classification: Anchor Details:In the 2014 Recommendations for Prestressed Rock and Soil Anchors (this is the Fifth Edition and is endorsed by the ADSC Anchored Earth Retention Committee) the Post-Tensioning Institute defines three classes of Cor-rosion Protection:PTI Class I: Encapsulated Tendons (often referred to as double corrosion protected, DCP)PTI Class II: Grout Protected Tendons (often referred to as single corrosion protected, SCP)Temporary: Grout Protected (often referred to as single corrosion protected, SCP)
